Adaline Neural Network and Real-Imaginary Instantaneous Powers Method for Harmonic Identification

Abstract

In this paper, a shunt active power filter (SAPF) is used for reactive power compensation and harmonic current suppression. Algorithm based on (ADALINE) Neural Network and Real and Imaginary Instantaneous Powers (ANN-RIIP) is developed in order to estimate and identify the harmonic terms individually and online. This algorithm is simulated in MATLAB/Simulink environment and implemented experimental in a dSPACE 1104 controller. The results obtained by simulation are in agreement with the experimental results confirming the effectiveness of the proposed ANN-RIIP algorithm. The results have also demonstrated that the speed and accuracy of ADALINE can improve the performances of active power filters.
